Getting Treatment

Pompe disease is a chronic disorder, in which the body does not produce enough of the acid alfa glucosidase (GAA) enzyme on its own. Lumizyme® (alglucosidase alfa) is a medication administered by intravenous infusion to provide a replacement for the missing enzyme directly into the bloodstream. Because Lumizyme does not correct the underlying genetic cause of Pompe disease, it needs to be administered on a regular basis to maintain a supply of the replacement enzyme in the body. Thus Lumizyme infusions may become a lifelong part of your treatment program.

The Treatment Experience

It is recommended that Lumizyme infusions are administered by a healthcare professional every 2 weeks, and each infusion lasts about 4 hours.  You’ll be monitored during the infusion for potential life-threatening reactions. During the infusion, you can do other things such as read, watch television, or visit with family and friends. It’s a good idea to talk to your doctor before you start treatment so you know what to expect and what kind of things you should alert your healthcare team about.  If you experience a severe allergic reaction during an infusion, the infusion may be stopped and you will receive appropriate medical care.

INDICATION

LUMIZYME® (alglucosidase alfa) is an enzyme replacement therapy for patients with Pompe disease (acid α-glucosidase (GAA) deficiency).

IMPORTANT SAFETY INFORMATION

WARNING: RISK OF ANAPHYLAXIS, HYPERSENSITIVITY AND IMMUNE-MEDIATED REACTIONS, and RISK OF CARDIORESPIRATORY FAILURE
  • If you or your child is taking Lumizyme, you should know that severe and potentially life-threatening allergic-type reactions known as anaphylaxis or severe hypersensitivity reactions, and other severe reactions related to the immune system may occur during and after Lumizyme treatment. Reactions may include, for example, kidney dysfunction, extreme difficulty breathing, shallow breathing, abnormal heart rate, low blood pressure, or throat tightness (including face, tongue and lip swelling) and skin lesions.
  • If you or your child experiences these severe reactions, you may require close observation during and after Lumizyme administration. You should discuss with your physician the signs and symptoms of anaphylaxis and hypersensitivity reactions and seek immediate medical care should they occur. Anaphylaxis or severe hypersensitivity reactions are potentially very dangerous. If such a reaction is severe enough, your doctor may decide to immediately discontinue the infusion and provide immediate medical care. Appropriate medical support measures may be administered when you are being infused with Lumizyme.
  • If your child has a current respiratory condition or illness and has compromised breathing or heart function due to Pompe disease, there may be risk of acute worsening of heart and/or lung function with Lumizyme due to the fluid of the infusion, and your doctor may decide that close observation during and after Lumizyme administration may be necessary.

WARNING AND PRECAUTIONS

Anaphylaxis and Hypersensitivity Reactions: Life-threatening anaphylaxis and hypersensitivity reactions have been observed in some patients during and after treatment with alglucosidase alfa. If such a reaction is severe enough, your doctor may decide to immediately discontinue the infusion and provide you with immediate medical care. Appropriate medical support and monitoring measures should be available during infusion.

Immune-Mediated Reactions: You or your child may be monitored for the development of systemic immune-mediated reactions while receiving Lumizyme. If these reactions occur, your doctor may discontinue the infusion and initiate appropriate medical treatment.

Risk of Acute Cardiorespiratory Failure: Infant Pompe patients with heart or breathing problems who are experiencing an acute respiratory condition may be at risk for increasing the seriousness of these problems as a result of Lumizyme administration due to the infusion fluid, and your child’s doctor may require additional monitoring for these infants.

Risk of Cardiac Arrhythmia and Sudden Cardiac Death during General Anesthesia for Central Venous Catheter Placement: Caution should be used when administering general anesthesia for the placement of a central venous catheter intended for Lumizyme infusion. Ventricular arrhythmias and slow heart rate resulting in cardiac arrest or death have been observed in infant Pompe patients with cardiac hypertrophy during general anesthesia for central venous catheter placement. Appropriate medical support and monitoring measures should be available during infusion.

Risk of Antibody Development: Since Lumizyme is a protein, it is the possible that patients receiving it develop antibodies. Some patients who develop high IgG antibody levels that last for a while may have reduced response to Lumizyme. Patients should be monitored for IgG antibody formation every 3 months for 2 years and then annually thereafter.

ADVERSE REACTIONS

The most frequently reported adverse reactions during Lumizyme studies in patients were allergy reactions and included: anaphylaxis, rash, fever, flushing/feeling hot, hives, headache, excessive sweating, nausea, cough, less oxygen in the blood, fast heart rate, rapid breathing, chest discomfort, dizziness, muscle twitching, agitation, bluish or purple skin, redness of skin, high blood pressure/increased blood pressure, facial paleness, chills, tremor, vomiting, fatigue, and muscle pain.

SPECIAL POPULATIONS

If you are pregnant, you should use Lumizyme only if your doctor has determined that its use outweighs any risks to your unborn child.
